LINEAR ACTUATOR

The purpose of the present invention is to provide a technology of having a stator and a front housing in a stable positional relationship without causing a cost increase. A linear actuator (100) is provided with: a stator yoke (115) having an end surface in the axis direction; a bobbin (113), which is disposed inside of the stator yoke (115), and which has a coil (111) wound thereon; a front plate (120) fixed to the end surface of the stator yoke (115); and a front housing (150) coupled to the front plate (120). The bobbin (113) is provided with a boss section (14) inserted into a hole that is provided in the front plate (120), the front housing (150) is provided with a boss section (152) passing through a hole that is provided in the front plate (120), and a leading edge of the boss section (152) is in contact with the end surface of the stator yoke (115). 本发明的目的是提供一种能够在不导致成本增加的情况下使定子与前壳体成为稳定的位置关系的技术。直线运动执行元件(100)具有：定子磁轭(115)，其在轴向上具有端面；绕线架(113)，其配置在定子磁轭(115)的内侧，并卷绕有线圈(111)；前板(120)，其固定在定子磁轭(115)的所述端面上；以及前壳体(
